Lantus question
We are using Lantus for the night time 24hr shot. We were told once
you open the bottle, you have to discard the extra after one month.
Is there a specific reason to do this or can I keep it longer. If I
throw it out after the month, I will waste 2/3 of the bottle. I keep
it in the refrigerator in the box. I was just wondering why you need
to throw it out that soon. If there are any suggestions out there, I
would appreciate the advice. Thanks.
